LOCK.

Specification of Letters Patent.

Patented June 29, 1920.

Application filed December 30, 1919. Serial No. 348,266.

To all whom it may concern:

Be it known that I, ALEXANDER BLOCK, a citizen of the United States, and resident of the city of New York, in the county of New York and State of New York, have in- In the lock embodying my invention, I

have provided a bolt and actuating means of simple construction, the initial step during the progress of locking the door being to move said bolt longitudinally into the keeper. The next step in the locking operation is to move said bolt in a direction to force a projection or hook on the outer extremity thereof into engagement with said keeper, thus interlocking the lock casing with said keeper. 7

Other objects and advantages will be pointed out and still others become apparent in the specification and claims.

In the accompanying drawings, Figure 1 shows a sectional elevation of the lock showing the disposition of its parts when in unlocked state. Fig. 2 is a sectional elevation of said lock showing the disposition of its par -s during the initial locking movement. Fig. 8 is a sectional elevation showing the disposition of the parts of the look when the locking operation has been completed. Fig. l is a sectional plan view of the lock shown in Fig. 3. V

The lock body proper comprises a metal casing, l, and locking mechanism contained therein; said casing being secured to a door by means of screws. Keeper, K, is secured to door frame DF also by means of screws. The door may be unlocked from the inside by turning a knob, l\' and from the outside by inserting key S in tumbler barrel T of the locking mechanism which passes through the door D. The keeper K is fitted onto the door frame Dr, so that its outer surfaces are flush with the surfaces of the frame. During the unlocked state, bolts, 1O 1O are positioned in the casing, the faces of the outer extremities of said bolts being flush with the edge of the lock casing. Said bolts being preferably rectangular in shape are provided with projections or hooks 10 10 on their outer extremities. At their inner ends said bolts are pivoted on a frame or plate 2 on studs 30-31; said inner ends respectively embracing stop projections 3283 abutting on studs 15-15 respectively. A link, 9, is pivoted by one end to one of the bolts and by its other end to the other bolt, thus yieldingly connecting said bolts, and rendering it possible to transmit movement from one of said bolts to the other. A spring 8 mounted on plate 2 bears down on said bolts and normally maintains their stop projections 3233 in abutment with stops 15-15 respectively, and nor- I mally tends to move the bolts l0 10 out of engagement with the keeper subsequently to the locking operations. The frame or plate 2 is or may be provided with a groove or grooves fitting over a horizontal tracknot sh0wncast upon the wall of easing 1, and thus guided in its horizontal movement; studs may also be provided for guiding said frame and thereby the bolts at all sides against lateral displacement and they may he therefore shifted in a direction toward or away from the keeper, as shown in Figs. 1, 2 and 3.

A. tumbler pawl 4 is pivoted upon frame 2 at 2 and is provided with a projection l normally bearing against a projection 2 on frame 2, and also comprises a ledge 4L abutting on a lug 17 and maintained in position by means or a spring 6 attached to its pivot head and leaning against a pin 6; by all of which means the bolts are maintained in their locked position. An arm 1% is mounted upon a sleeve 14 revolubly mounted in casing 1; a knob N attached to said sleeve is adapted to rotate said arm let to bear against projection l of pawl and release ledge at from lug 1?, said arm then continuing in its further progress to impinge against a proj ection 2* on frame 2 to move the bolts out of the lock casing into the keeper, when the tumbler pawl 4L descends to bring ledge 4 into abutment with lug 17 to maintain said bolts in said position. To return bolts 10 1O the knob N is turned in the opposite direction when'arm 14 is made to impinge against projection 2 of frame 2 after releasing said frame by bearing against proj ection 4 of tumbler pawl 4. Another arm 20 is mounted upon a spindle 20 connected with tumbler barrel T operated from the outside of door by a key S, which when turned rotates arm 20 to the same purpose as knob N on its arm 14to shift the bolts ID -10 into and out of the keeper.

This initial step in the locking operation, that is, the shifting of the bolts into the keeper, is accomplished by turning the knob N or key S through approximately one half revolution; As said knob or key continues in its progress to complete its revolution, the respective arms, 14 or 20, actuate certain mechanism which bear upon bolts 1O 1O to move them in a direction to force their vertical projections or hooks or secondary bolts 10 -10 into recesses R and R re spectively provided for that purpose in the keeper and thus to interlock the casing 1 with keeper K. Said interlocking mechaanism embraces a frame or plate 3 provided with a groove or grooves, not shown, fitting on track or tracks, not shown, cast on casing 1, for guiding said frame against lateral displacement in its movement toward or away from keeper K. A tumbler pawl 5 is pivoted upon frame 3 at 5 and comprises a projection 5 normally bearing against pro ection 3 on frame 8, a ledge 5 on pawl 5 abuts on a 111 116 on casin 1 and a serumin c: 1 I z:

7 attached to its pivot head is adapted to maintain pawl 5 in position, said spring,

leaning against pin '7. A lever 11 pivoted at 12 embraces an arm 11 embracmg a cam rounded surface adaptable for bearing against bolt 10 and an arm 11 to which is pivoted one end of a link 13, the other end of which link is pivoted to frame or plate 3. Any movement transmitted to said frame 3 will cause lever 11 to swing toward or away from the keeper depending upon the direction in which frame 3 is caused to move, and thus cause the bolts tomove into engagement with the keeper a spring 8 being provided to move said bolts out of engagement with said keeper after said bolts have been released by said lever.

To look the door, the key or knob mechanism is turned through a complete revolution. While describing the first half revolution, arm 1d bears first on projection P of tumbler pawl 4 and releases ledge 4 from lug 17; the arm then bears against frame projection 2 and moves the bolts longitudinally into locking position. Subsequently to the locking operation, arm 14, in completing the revolution, first bears against tumbler pawl5 to release ledge 5 from lug 16, then bears against projection 3 of frame 3 and moves it in a direction to actuate lever or cam 11, to in turn cause said lever to bear against bolt 10 and transmit said movement from said bolt to bolt 1O through link 9 so that the bolts and their hooks are moved into engagement with the keeper. To unlock the door the motion is reversed.
